YDTech® manufacturer of precision shafts ,needle rollers pins (GCr15, SUJ2, 100Cr6, SAE52100)! supplier of miniature shafts,cylindrical rollers,needle rollers (GCr15, SUJ2, 100Cr6, SAE52100) in china.

Needle rollers are small cylindrical rollers with a length that is typically several times their diameter. They are often used in needle roller bearings, which are used to reduce friction and facilitate motion in various applications. Needle rollers are typically made from hardened steel or other high-strength materials, and are capable of supporting high loads while maintaining a small profile.

Mini shafts, on the other hand, are small shafts that are used to transmit torque or motion in mechanical systems. They are typically made from materials such as steel, aluminum, or other metals, and come in a variety of lengths, diameters, and shapes. Mini shafts are often used in precision systems such as robotics or instrumentation, where precise motion control is critical.

needle rollers are small cylindrical rollers that are used to reduce friction and support loads, while mini shafts are small shafts that are used to transmit torque or motion. While there may be some overlap in the applications for these components, they serve different functions and are designed to meet different requirements.

Needle rollers and grooved pins are both used as components in various mechanical systems, but there are some key differences between these two components.
